Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell activation devices, in particular to a PEM water electrolysis electrolytic cell activation device. Background Art

[0002] Hydrogen energy is a clean, efficient, renewable energy source. Using hydrogen energy to replace fossil energy is considered an effective way to solve the energy shortage and environmental pollution problems currently facing the world. Water electrolysis is one of the most effective technologies for producing high-purity hydrogen. Especially when combined with renewable energy power generation technology, it can not only effectively absorb "abandoned electricity" and has good economic efficiency, but also realize a cleaner hydrogen production method, which has broad application prospects.

[0003] Proton exchange membrane (PEM) water electrolysis hydrogen production device has become a new generation of water electrolysis hydrogen production device due to its advantages of small size, compact structure, strong pressure resistance, large working current and high hydrogen production purity. In actual operation, PEM electrolyzer needs to be activated for a long time in order to reduce the transmission impedance of protons, improve the transmission channel of proton water, gas, etc., so that the performance of the electrolyzer can be stabilized and the activation efficiency can be improved. However, this activation time is long and requires continuous load, resulting in high pure water and electricity costs and low efficiency. Poor control of temperature and water flow may affect the shedding of the membrane electrode catalyst layer, resulting in limited life.

[0004] The activation process in the prior art generally involves placing the electrolyzer directly on a test platform, then heating it and applying a gradient current to fully activate it. This activation method requires repeated switching of constant current and constant voltage, and the operation is complicated. In addition, some test platforms do not propose one-piece or integrated equipment for the activation process of PEM electrolyzers. Therefore, the activation process is mostly disordered and irregular, and the operation is inconvenient, which is also one of the main reasons for low efficiency. What is more serious is that the poor selection of activation process and equipment will also cause problems such as poor bonding between the catalyst layer and the proton exchange membrane during the use of the electrolyzer, thereby increasing the resistance, affecting the activity of the membrane electrode, and restricting the performance of the PEM electrolyzer. Utility Model Content

[0008] On this basis, the hydrogen warehouse, strong electric field warehouse and storage warehouse are all equipped with transport racks for placing transport carts. One end of the transport rack is rotatably connected to the opening of each warehouse body, and the other end is controlled by a cylinder to perform lifting movement within the warehouse body.

[0009] On this basis, one end of the transport frame located in the warehouse body is provided with a protective fence for the transport trolley.

[0010] On this basis, a plurality of cylinders are arranged in an array on the guardrail.

[0011] On this basis, the transport trolley is made of high temperature resistant material, and the surface is coated with insulating paint and waterproof paint in sequence.

[0012] On this basis, the hydrogen warehouse, the strong electric field warehouse and the storage warehouse are all provided with sealing covers.

[0013] On this basis, a ramp plate is arranged at the joint of the lifting platform.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model realizes independent step-by-step treatment of the electrolytic cell by setting up a hydrogen warehouse, a strong electric field warehouse, and a storage warehouse. Nitrogen is first introduced into the hydrogen warehouse to replace the air to avoid explosion.

[0017] (3) In the utility model, the electrolytic cell can be moved forward and backward in each bin by lifting the transport frame, which saves time and effort. At the same time, a rotating connection type transport frame is adopted, that is, one end of the transport frame is connected to the transport track, which makes it easier for the transport trolley loaded with the electrolytic cell to enter the transport frame more smoothly.
